Abstract
In the color-string model, the impact of string percolation on multiplicities,
,
and their long-range (forward-backward) correlations is studied.
It is assumed that different string overlaps produce the observed hadrons
independently. The multiplicities are shown to be damped by a simple factor
which follows from the percolation theory. The
rise at the same rate
as multiplicities fall.
A clear signature of the percolation phase transition is found to be the
behavior of
the forward-backward correlations for intensive quantities, such as
or
its
inverse, which can be detected in the relativistic heavy-ion collider.
